Problems solved by technology

These functions and designs may cause 5G base stations to generate greater radiation to users (according to conservative estimates, the safe distance between 5G base stations and the human body is 100 meters)
Moreover, the design of high power, large bandwidth, and multi-antenna itself will also cause a large power consumption of the 5G base station, resulting in a large operating cost of the base station

Abstract

The present application provides a power adjustment method and device, which relate to the field of communications and can reduce the transmit power of a base station, thereby reducing radiation and power consumption of the base station. The method includes: obtaining signal-to-interference-plus-noise ratio SINR values ​​of multiple terminals; determining the proportion of the first terminal among the multiple terminals; wherein, the first terminal is at least one terminal whose SINR value is greater than a first threshold; if the first terminal If the proportion of the first terminal among the multiple terminals satisfies the first preset condition, the transmission power between the base station and each terminal is adjusted according to the first preset rule; if the proportion of the first terminal among the multiple terminals satisfies The second preset condition is to adjust the transmission power between the base station and each terminal according to the second preset rule; if the proportion of the first terminal among the multiple terminals satisfies the third preset condition, then the The transmission power between the base station and each of the terminals is adjusted. It is used to adjust the transmit power of the base station.

Description

technical field [0001] The present application relates to the communication field, and in particular to a power adjustment method and device. Background technique [0002] The current 5G standard has been basically determined. The future 5G base station will be a new base station formed by combining high power (200W), large bandwidth (100MHz) and massive multiple-input multiple-output (MIMO) antenna technology. And the 5G base station has the ability to perform beamforming on multiple subcarriers. This capability means that at the transmitting end, the beamformer controls the phase and signal amplitude of each transmitting device to obtain the required constructive and destructive interference patterns in the transmitted signal wave array. At the receiving end, the signals received by the different receivers are combined in an appropriate way to obtain the desired signal radiation pattern. These functions and designs may cause 5G base stations to generate greater radiatio...
